UNITED STATES PATENT OFFICE. I

LOUIS F. KATONA, OF LOS ANGELES, CALIFORNIA, ASSIGNOR OF ONE-HALF TO FRANK C. WOLF, OF LOS ANGELES, CALIFORNIA.

BOTTLE-WASHING MACHINE.

To all whom it may concern:

Be it known that I, LOUIS F. KATONA, a citizen of Hungary, residing at Los Angeles, in the county of Los Angeles and State of California, have invented new and useful Improvements in Bottle-WVashing Machines, of which the following is a specification.

This invention relates to bottle washing machines.

An object of the invention is to provide a bottle washing machine of great simplicity and at the same tim of low power consumption, and a special object is to provide an improved bearing means and lubricating means for the shafts of the machine which drive the bottle scrubbing brushes.

Other objects and advantages will be made manifest in the following specification of embodiments of the invention illustrated in the accompanying drawing, where- 1n:

Fig. 1 is a plan of the machine, with the cover in section.

Fig. 2 is a vertical section on the line 22 of Fig. 1.

Fig. 3 is a plan showing a modified form of the bearing.

The present invention includes a motor M, preferably an electric motor having on its shaft a pinion 2 which engages a central gear 3 of a set of three gears. Each gear 3 is fixed on a shaft 4, these shafts being arranged parallel to one another and having on their forward ends suitable chucks 5. These chucks are adapted to grip spindles 6 of brushes 7. When a bottle B is thrust over the inner brush as indicated in Fig. 1, the outer brushes clean the outside of the bottle;

An important feature of the present invention consists of means for mounting the shafts 4. This means includes an integral pillar block 10 through the ends of which pass screws 11 clamping it to a bed 12 upon which the motor M is also firmly secured. The block 10 is of suitable dimensions and integrally formed therewith is a set of three substantially cylindrical chambers 10 through which the shafts 4 extend respectively. To obtain ease of operation and effective lubrication there is provided in each end of each chamber 10 a ball-bearing device 13 including outer rings which are firmly clamped in the chambers 10 by screws 14 passing through upwardly extending lugs 15 formed in pairs as clearly shown in Fig. 1. To obtain the necessary flexibility of the lug portions of the chambers 1O these latter are transversely slotted at 10 with the result that the clamps, screws or bolts 14 when screwed up draw the spaced lugs 14, of each pair, toward each other to bind the interposed bearings 13.

From the above, it will be seen that by making the several bearings for the shaft 4 in one integral structure a desired degree of rigidity is secured and at the same time vibration is reduced and strength main tained, all with a high degree of simplicity, ruggedness and low cost. Lubrication is secured by attaching to the top of each shaft chamber 10 a grease or other lubricant cup 16 from which the lubricant can, at intervals, be discharged onto the shaft 4 in each chamber.

The gearing, together with the bearing block, is concealed at the front end and top of a simple shell 17 having a front wall 18 through which the clutches 5 project. The shell 17 may extend sufficiently rearwardly to cover the motor M.

The chamber 10 extends upwardly from th body of the block or plate 10 thus obtaining a sufiiciently strong structure and light weight at the same time.

The chamber 10 forms a housing for the ball bearings 13 and at the end of the longitudinal split over the ball bearings there is a transverse split 16 (See Figs. 1 and 2.) This allows the screws 14 to squeeze the outer end of the chamber 10 tightly on the ball bearings without warping the central portion containing the grease cup 16.

In Fig. 3 a bearing chamber or shell 10 is shown as longitudinally split to permit the construction of the clamp lugs. The chucks 5 have flanges 5 within the front wall 18 which operate to throw off anymoisture following along the chucks and therefore preventing the moisture from getting to thebearings.

Further embodiments, modifications and variations may be resorted to within the spirit of my invention.

What is claimed is:

1. A bottle washing machine having an anti-friction bearing composed of a housing, a ball bearing at the end of the housing a longitudinal split in the housing adj a-' cent the ball bearing, :1 transverse split at the inner end of the longitudinal split, means to clamp the housing at the longitudinal split and thereby firmly hold the ball bearing, and a brush driving shaft in the said ball bearing.

2. A bottle Washing machine having an anti-friction bearing composed of a housing, a plurality of ball hearings in said hous ing, a longitudinal split in the housing adjacent each ball bearing, a transverse split in the housing at the end of the longitudinal split bolts to clamp the longitudinal split portions of the housing and thereby firmly hold the ball bearings, and a brush driving shaft in the ball bearings.

In testimony whereof I have signed my nam to this specification.

LOUIS F. KATONA.
